Abstract
The present disclosure relates, according to some embodiments, to methods and systems for impregnating wood with a polymer solution and products thereof. In some embodiments, the present disclosure relates to a method of processing a wood piece to generate a wood product, the method comprising: (a) placing the wood piece into a reactor having a chamber pressure of a vacuum environment; (b) exposing the wood piece to a polymer solution; (c) performing an iterative process where each cycle of the iterative process comprises a pressurizing period during which the chamber pressure is increased to an increased chamber pressure and a stabilizing period during which the chamber pressure is monitored to measure a chamber pressure decrease, if any; (d) when the decrease of chamber pressure during the stabilizing period is less than or equal to the certain threshold change, normalizing the reactor chamber to a normalized pressure; and (e) setting the wood piece to generate the wood product. The present disclosure further relates to a wood product generated by a method of processing a wood piece.
